Does anyone have any medical advice on how I tested positive for oxy-codone, but none of my medications contain it. Medications include cytomel, rythmol, warfarin, toprol, and hydrocodone. They tell me that none of the above qualify, and I am at a loss as to how this is showing, having never (knowingly) done it. My job of 18 years, is in danger as well as any possibility of getting hired somewhere else if I explain why I left such a good job.
